AIM: To analyze the clinical curative effect and operation complications in the process of extracapsular extraction of cataract by phacoemulsification.

METHODS: Totally 4 350 cases of cataract were treated by sclera tunnel incision phacoemulsification cataract extraction, and the reason of the operation complications was analyzed. The patients were followed-up for 3-24 months.

RESULTS:Phacoemulsification was performed successfully on 4 345 eyes(99.89%), and 5 eyes were changed to extracapsular cataract extraction combined with intraocular lens(ECCE+IOL)implantation. 10 eyes(0.23%)attained corrected vision under 0.1; 290 eyes(6.67%)attained corrected vision of 0.1 to 0.4; 4 050 eyes(93.10%)attained corrected vision of 0.5 or better 3 months after operation. During the operations there were capsular rupture in 26 eyes(0.60%), defeated capsulorhexis in 16 eyes(0.37%), corneal endothelial edema 350 eyes(8.05%), posterior capsular opacification 116 eyes(2.67%), intraocular hypertension 31 eyes, entophthalmia in 3 eyes.

CONCLUSION: The extraction of cataract by phacoemulsification and embedding of artificial crystal may have less tissue damage, and vision recovers quickly. Though it is an effective method, understanding the reasons for operation complication and reducing the operation complication can ensure the success of operation.
